Rotary electric vibrators use an electric motor to turn shaft mounted eccentric weights to produce rotary vibration. The heavier the weights and the faster they turn, the greater the centrifugal force produced. Electric vibrators are much more quiet and efficient than pneumatic or hydraulic rotary vibrators. Global QT and DEG Series electric vibrators are available in 2 pole (3600 RPM) and 4 pole (1800 RPM) and in various voltages for single and three-phase AC current.

When harnessed by proper mounting of the electric vibrator, rotary vibration is transferred through the hopper or bin wall to the material within. As the material vibrates it is displaced from the hopper wall reducing friction and allowing gravity to restore material flow. Proper mounting also disperses the rotary vibration over a large area producing uniform material flow. Since rotary vibration is directional, material will be encouraged to flow in the direction of the rotating weights.

Applications:

• Quiet Thunder® electric rotary vibrators produce vibration of low to medium frequency and a wide range of forces up to 5,000 pounds of centrifugal force. This makes them well suited for moving a wide variety of fine to coarse mesh materials in all sizes of bins and hoppers.
• They are especially useful where air or hydraulic power sources are not available and where quiet operation is necessary.

Features:

• Produces Uniform, Directional Flow.
• Quiet Operation - Only noise is the hum of the electric motor.
• Highly Efficient - Less expensive to operate than pneumatic vibrators.
• Adjustable Force Settings - Centrifugal force settings can be quickly and easily changed, without the need for special tools, to accommodate different loads.
• Built in Thermal Protection - QT2-80 and QT2-160 models only. QT2-80 model is fan cooled.
• Shock Resistant Motor Windings - Epoxy encapsulated to withstand vibration.
• Permanently Sealed, High Capacity Bearings - Require no lubrication.
• Heavy Duty Construction - Rugged ductile iron housings on larger DEG models. Lightweight aluminum housings on smaller QT models.
• Weather Tight Construction - Units sealed with silicone to keep out contaminants.
• Easily Repairable - Easy disassembly. Bearings, o-rings, retaining rings are standard parts commonly available from your local bearing distributor. Rotors and stators replaceable on most models.
• Three-Year Warranty.

Options:

• 115 / 230 Volt Single Phase - QT2-80 and QT2-160 available in 115 volt only.
• 230 / 460 Volt Three Phase - Except for QT2-80 and QT2-160.
• 575 Volt Three Phase - Except for QT2-80 and QT2-160.
